Secure Boot Violation - Invalid Signature detected. Check Secure Boot Policy in Setup.

Hi,

When I turned my Anotebook this morning, there was a Windows update. After it was installed I got this message "Secure Boot Violation - Invalid Signature detected. Check Secure Boot Policy in Setup." in a red box. It is the first thing that appears on screen.

I then press OK to get to the next screen (with Main, Advanced, Boot, Security and Save & Exit tabs).

I've read some other similar cases where Microsoft was advising to disable the Secure boot control, which I did. I also tried and deleted all the keys and install new ones from factory but I can't do anything about the "DBT one". When I try to "Set new DBT"
and then press "OK" it just doesn't change anything and it's the only one that is "not installed".

I've seen people talking about CSM in the "Boot" tab but all I have in mine is "BOOT OPTION #1" > "Windows Boot manager" / "Disabled".

Can you help me?

I run Windows 10 (originally 8 I think) on it.

Thank you
